Heretofore this reagent', Fig. 3, an inverted plan and sectional view o usually soda-ash, has been contained in a the chemical-solution pipe and the cold-watank placed wholly exterior to the purifying ter-supply pipe, showing the perforations apparatus and a solution of the reagent was therein.

The first was the formation No. 322,911, for water-purifying apparatus, of incrustation in the pipe for conveying the and comprises a process for accomplishing solution from the tank tothe purifying appathe objects' above set forth. This process ratus. This difficulty has led to various inconsists in producing or generating a reagent ventions or efforts to prevent this incrustachemical solution for acting on the water in to effect the collection of the imroduction or generation being and under the inthe purifier urities, such done inside of the purifier fluence of purifier, and

To overcome this difficulty, resort has been had to efforts to find a place in the cold-water pipe or in the purifying apparatus near the pipe where the back pressure of thefeed-water would not oppose e in introducing this solution in a heated state into the water to be purified. Our process further consists in conducting the solution from the place of prolductionor eneration to the place of intermixing with n introduction of the solution into the urifythe water to be purified under and while subing apparatus Thus these several ifficuljected to the heat in the purifier, this step beties have led to expensive and. cumbersome ing practiced when the p oint of mixing e tirely avoid all such difficulties and entirely solution with the water is more or less remethods for Overcoming or attemptingl to overcome them. By our invention we enmote from produced or generated, d la further step in our process consists in intermiXing this heated 4solution with the water to be purified just rior to the distribution of the water over the purifying-pans.
